These classic Danish butter cookies are crisp at the edges with tender, melt-in-your-mouth centers and rich buttery flavor. Simple techniques ensure beautiful swirls, pale-gold color, and bakery-style aroma.
Store completely cooled cookies in an airtight tin at room temperature for 1–2 weeks, layering with parchment. To freeze baked cookies, freeze in layers with parchment for up to 2 months and thaw uncovered at room temperature. To freeze dough, pipe swirls on a parchment-lined tray, freeze solid, then bag for up to 2 months; bake from frozen, adding 1–2 minutes. For best swirls, use very soft butter and a large star tip. Avoid overbaking; aim for pale golden edges. If dough is too loose or warm, chill 15–20 minutes; if still spreading, add 1–2 tablespoons flour. Use high-quality chocolate for dipping and don’t skip the pinch of salt for flavor.
